This patch extends the proc entry to contain a possibility to view and change the output devices for each IGA. This is useful for debugging output problems as it provides a reliable way to query which low level devices are active after VIAs output device configuration nightmare happended. It's as well suitable for daily use as one can change the output configuration on the fly for example to connect a projector. At the moment it's still unstable. The reason is that we have to handle a bunch of undocumented output devices (those without a proper name) and that this patch is the first step to collect and verify the needed information. Basically the only configuration change that is expected to work at the moment is switching output devices between IGA1 and IGA2.
